Helo Cyfeillion y Gwanwyn,

Diolch am eich gwaith ar yr ymchwiliad Bylbiau Gwanwyn i Ysgolion. Rwyf wedi mwynhau darllen y sylwadau sef wedi ei rhannu hefo'r data tywydd. Diolch am eich negesau, ac rwyf yn gobeithio bod chi yn mwynhau'r prosiect. 

Mae nifer ohonoch wedi rhoi gwybod bod eich planhigion wedi cychwyn tyfu. Mae hyn yn newyddion gwych! Plîs cymrwch luniau a rhannwch dros Twitter neu mewn e-bost.

Mae eich planhigion yn tyfu:

Albert Primary School: The temperature changed throughout the week and there was a lot of rain. We think the bulbs may be starting to sprout.

Carnbroe Primary School: The plants are growing well.

Sandal Magna Community Academy: Some of our plants have started to grow leaves.

Ysgol Bro Pedr: A lovely dry week, apart from Friday. Our daffodil bulbs are starting to grow - exciting

High Cross Primary School: Hi professor plant the class’s plants are growing quite fast.

Hendredenny Park Primary: Hello, we can see little sprouts in our pots. There was no dead fly’s this week but there was a little bit of dirt .Bye

Hendredenny Park Primary: Some plant have started to sprout out of the soil.

High Cross Primary School: Hi professor plant the class’s plants are growing quite fast.

Sylwadau am y tywydd:

Ysgol Ysbyty Ifan: Glaw trwm iawn a llifogydd yng Ngogledd Lloegr ddoe. Ond nid mor ddrwg yma. Pawb yn sgubo dail yr Hydref oddi ar yr iard ddoe a heddiw am ei bod yn oerach. Bl 3 a 4 wedi casglu'r afalau oddi ar ein coeden 5 Kilo! Tarten wysnos nesa! Athro’r Ardd: Da iawn Cyfeillion y Gwanwyn. Rydych wedi bod yn brysur!

Ferryside V.C.P School: Roedd y tywydd wythnos hon yn heulog ac yn oer. Dim ond 4ml o law a nowsweithu oer.

Arkholme Primary School: We had a lot of rainfall this Thursday, Maisie and I really enjoyed collecting the data this week. Unfortunately Mr Bonwick's Plant pot got knocked over, not much sign of any growth. Professor Plant: I’m sorry to hear one of your pots was kicked over! I’m glad to hear that you are enjoying the project though.

Saint Anthony's Primary School: The temperature gradually decreased until Friday when it dropped sharply. Professor Plant: Gosh bulb buddies, a drop from 8 to -2 in temperature!

St Fergus' Primary School: It has been very windy, cold and stormy this week.

Darran Park Primary: We've lots and lots of rain. Today we had hail stones at lunch time. It feels very cold in the wind.

Bursar Primary Academy: We had 130ml of rain on Monday, 124ml on Thursday. Lincolnshire has had a large amount of rain.

St Fergus' Primary School: The flower beds and pots look tidier but there are still more leaves to be cleared. It was a mix of weather this week with some rain at the beginning of the week and then got colder at the end of the week. The frost stayed most of the day today (Friday).

Ysgol Bro Pedr: What a beautiful end to the week. Much better than the damp miserable weather at the start.

Oldfleet Primary School: Warmer all week but lots of wet play times

Stoneferry Primary School: Another rain-filled week!

Georgetown Primary (Tredegar): There was snow on Wednesday night from about 7.30pm. When we got up on Thursday everything was white. It started to rain and the snow cleared.

Arkholme Primary School: We have noticed that on Monday there was a very high rainfall. We had 3 very frosty nights at the start of the week. We have really enjoyed taking the reading.

Aberdare Park Primary School: We had a fall of snow on overnight on Wednesday. This turned to sleet early Thursday morning and then rain.

Darran Park Primary: We had some snow on Wednesday evening. It was really cold.

Henllys CIW Primary: The temperature stayed fairly consistent and the rain was weird due to the fact that it was wet on Monday, getting dryer and dryer until Thursday when it rained really hard and then all the way back to zero.

Stanford in the Vale Primary School: What a week of heavy rain and we experienced the chill factor also - starting to get cold!

Ysgol Bro Pedr: A mixture of all weathers this week - snow, sunshine, rain, frost, hailstones, wind!!!

Hudson Road Primary School: It felt chilly this week and cold. On Friday it was very rainy and it is supposed to snow!

Bardney Primary School: Rain fall on Friday 8th was actually 23mm but no option from drop down box. Rounded to the nearest 10. Professor Plant: Well done Bulb Buddies, that’s exactly what you need to do. Keep up the good work

Clifton Primary School: This is the first year we have been involved in the bulb project and we have really enjoyed our first week! On Thursday/Friday, Hull had an awful lot of rain which made measuring the rainfall quite interesting. We're looking forward to seeing everyone's results.

Bryncoch CiW Primary School: We have rounded the rainfall to the nearest 10mm

Professor Plant: Well done Bulb Buddies, that’s exactly what you need to do. Keep up the good work

Dalbeattie Primary School: On one day there was lots of drizzle but the next rainfall reading did not show anything other than a few droplets. Presumably, during the 24 hour period between readings, some of the water had evaporated out of the rain gauge? ProfessorPlant: That’s right Bulb Buddies.

Darran Park Primary: We have noticed that the temperature is getting colder.

Stanford in the Vale Primary School: Hello its Riley. We have planted all our bulbs and have been observing the rainfall and temperature this week - hardly any rain and we have said it’s getting colder - goodbye and have a nice weekend - Regards Riley

Stoneferry Primary School: Massive amount of rainfall this week - bulbs have had a lot of water. Children loved inputting the data with the teacher.

Mae Riley, ddisgybl yn Ysgol Stanford in the Vale, wedi cymryd rhan yn yr ymchwiliad Fylbiau'r Gwanwyn i Ysgolion am y tair blynedd diwethaf. Mae wedi dangos ymrwymiad arbennig i'r prosiect, ac mae wedi gwneud argraff fawr ar gydlynydd y prosiect drwy ei adborth disgrifiadol a chyfeillgar. Mae'n rhaid i mi ddweud, rhwyf wedi mwynhau darllen diweddariadau wythnosol gan Riley dros y tair blynedd diwethaf.

Dyma rai o sylwadau gorau Riley:

2017:

• The weather has turned really cold today. Been training people to do this experiment during the week. From Riley xxx
•  Hello. This week it has not been icy and it has been nice all except today. Hope you have had a nice week. Bye Bye (Riley)
•  Hello, this week it has been cold and hot and it has been a really good week because we have had a delivery of two new trolleys and we even invested in a wormery which is a big hit with our foundation friends. (Riley)

 2018:

• Hi this is Stanford in the vale primary school, we done this amazing project last year .I am Riley one of the gardening club members. I was the one that recorded and submitted this data last year. I loved doing this project last year, I hope I will this year too. I will be also teaching some of my friends how to do this project this year too. Bye Bye Riley (Riley)
•  Cannot believe this is the last weather reading for this year! We have observed some strange weather patterns this year! Snow - sunshine! (Riley)

 2019:

• Happy to restart the project and I am teaching the younger children in the club how to record. Have a good weekend and we will be back next week. Regards Riley (Riley)
• HI THERE, this week it has been a mixed week and there has been a lot of rain this week and there has been a bit of sun. Today in class we were talking about global warming which is a serious issue which needs to be sorted out. Speak to you next week!

I ddathlu cyfraniad Riley i'r prosiect, fe ofynnon ni a fyddai'n hapus i ateb rhai cwestiynau a rhoi cipolwg i ni o'i brofiad o gymryd rhan yn yr ymchwiliad.

Cyfweliad gyda Riley:

Q. How long have you been involved with the Spring Bulbs for Schools Investigation?

A. I have been involved in this investigation for three years now.

Q. What have you enjoyed most about the project?

A. I’ve mostly enjoyed recording the weather and the rain. I like seeing the difference between the temperatures of different days.

Q. What do you feel you have gained from the project, have you developed new skills?

A. Yes, I do think I have gained on this project. I have developed how to record the rain using a gauge and it has helped me using a thermometer more accurately.

Q. What are your thoughts on Science and Maths?

A. I am quite interested in both of these subjects, so this has helped me produce a lot more in these subjects.

Q. What were you feelings towards these subjects before the project, have they changed?

A. I was feeling quite confident before I started and now I am feeling much more confident about it.

Q. Were you aware that you were doing math and numeracy during the project?

A. I was sort of aware that I was using maths and numeracy during the project. I was mostly aware as I was measuring in millimetres and degrees.

Q. Were you confident taking scientific measurements before the project?

A. I was a little confident but I wasn’t that sure on it but now I am really happy about it.

Q. Do you feel these skills have developed through your time on the project?

A. Yes definitely, before I wasn’t that sure mostly on how to measure the rain and this project has developed my skills on that and developed my skills also in science.

Q. What advice would you give us to improve or develop the project?

A. I think it would be good fun if you could give the children some more fun activities or competitions because at the moment you don’t have many.

Q. You took a leading role, teaching other pupils about the project. Can you tell us a little bit about that experience?

A. I think it is really fun / exciting teaching other children about this experiment because it makes me feel like it is helping other children develop their science / maths and it makes me think that they could take over the job and become future scientists! 

Rydym wedi cymryd cyngor Riley, a byddwn yn edrych ar weithgareddau a chystadlaethau newydd y gallwn eu cyflwyno dros y blynyddoedd nesaf.

Riley yw'r cyntaf i gael ei henwebu fel Pencampwr Bylbiau'r Gwanwyn. Yn y dyfodol, byddwn yn gofyn athrawon i enwebu disgyblion sydd wedi dangos ymrwymiad rhagorol neu wedi datblygu fel canlyniad o'r prosiect, i gael eu cydnabod fel Pencampwr Bylbiau'r Gwanwyn.

Diolch Riley, a phawb a gyfranogodd i'r prosiect eleni.

Clod uchel:

Helo Cyfeillion y Gwanwyn,

Diolch i bob ysgol sef wedi rhannu cofnodion blodau! Cofiwch i wneud yn siŵr bod y dyddiad yn gywir a bod taldra'r planhigyn wedi ei chofnodi yn filimedrau. Rydym wedi cael cofnodion yn dangos bod planhigion wedi blodeuo ym mis Ebrill a hefo disgrifiadau am grocws a chennin Pedr anhygoel o fyr!

Os ydych yn gweld bod eich cofnodion yn angen ei chywiro, yna yrrwch rhai newydd i mewn hefo esboniad yn y bwlch sylwadau.

Rwyf wedi mwynhau darllen y sylwadau hefo’r cofnodion tywydd a chofnodion blodau dros y pythefnos diwethaf. Rwyf wedi atodi rhai o’r sylwadau yn isod. Wnaeth Ysgol Stanford in the Vale gofyn cwestiwn da flwyddyn ddiwethaf,  'oes rhaid i gofnodi pob blodyn i’r wefan, beth os mae'r dyddiad a’r taldra'r un peth?' Mae’n bwysig i rannu’r cofnodion i gyd oherwydd mae'r nifer o blanhigion sydd yn blodeuo ar ddyddiad unigol a’r taldra'r planhigion yn effeithio ar ein canlyniadau.

I weithio allan taldra cymedrig eich ysgol ar gyfer y crocws a’r cennin Pedr, ychwanegwch bob taldra a rhannwch hefo'r nifer o gofnodion. Felly, os oes genych deg cofnodion o daldra i’r crocws, ychwanegwch y rhain a rhannwch hefo deg i gael y rhif cymedrig.

Os oes gennych un blodyn hefo taldra o 200mm ac un blodyn hefo taldra o 350mm, fydd y rhif cymedrig yn 275mm. Ond, os oes gennych un blodyn hefo taldra o 200mm a deg hefo taldra o 350mm fydd y rhif cymedrig yn 336mm. Dyma pam mae’n bwysig i gofnodi pob planhigyn.

Mae pob cofnod blodyn yn bwysig ac yn cael effaith ar y canlyniadau. Os nad yw eich planhigyn wedi tyfu erbyn diwedd mis Mawrth, plîs wnewch gofnod data heb ddyddiad na thaldra ac esboniwch hyn yn y bwlch sylwadau. Os mae eich planhigyn yn tyfu, ond ddim yn blodeuo erbyn diwedd mis Mawrth, yna plîs cofnodwch daldra'r planhigyn, heb ddyddiad blodeuo, ac esboniwch hyn yn y bwlch sylwadau.

Cadwch y cwestiynau yn dod Cyfeillion y Gwanwyn! Mae 'na nifer o adnoddau ar y wefan i helpu hefo’r prosiect. Unwaith mae eich planhigyn wedi blodeuo, fedrwch greu llun ohono a defnyddio hyn i labelu'r rhannau o’r planhigyn! Hoffwn weld ffotograff o rain a rhannu nhw ar y blog nesaf.

Ar y nodyn hwnnw, hoffwn rannu fideo Ysgol Llanharan gyda chi, cliciwch yma!

Daliwch ati gyda’r gwaith caled Cyfeillion y Gwanwyn,

Athro’r Ardd
